Abstract

A method of diagnosis of a living organism by providing at least one functional map of the living organism, the method having the steps of determining at least two physical parameters characterizing the physiological state of the living organism, recording spatial-temporal distributions of the at least two physical parameters, acquiring and processing information about the spatial-temporal distributions of the at least two physical parameters, and utilizing the information about the spatial-temporal distributions of the at least two physical parameters to generate the at least one functional map of the living organism. Further steps include using one of the at least two physical parameters as a reference for selecting another of the physical parameters, substantially simultaneously recording the spatial-temporal distributions of the at least two physical parameters or recording the spatial-temporal distributions of the at least two physical parameters at a preselected time interval apart from one another.
